摘　　要：在一些特殊应用中,控制电路被封装或分散安装,无法利用烧写器进行现场更新。本文提出了一种基于IAP(在应用编程)的STM32控制电路远程升级方案。该方案结合了IAP技术、RS-485通信协议和Ymodem传输协议,确保了程序的实时更新和数据传输的可靠性。实践证明该设计方案具有在线升级成功率高、文件传输完整性好等特点。In certain specialized applications,the control circuits are encapsulated or installed in dispersed locations,and the on-site updating via a programmer is impractical.This paper proposes a remote firmware upgrading solution for STM32 control circuits by utilizing IAP(In Application Programming).The proposed approach integrates IAP technology,the RS-485 communication protocol and the Ymodem transfer protocol to ensure real-time program updating and reliable data transmission.The eperimental results show that this design scheme achieves high success rate in online upgrading and excellent integrity file transfering.
